In a test on a 6 "diameter light oxidation cast iron conduit where the flow rate was 26.5 l / s, the pressure was measured at two points a and b, distant from 1017 m where values of 68.6.104n / m2 and 20.6.104n / m2 respectively. considering that the difference in quota between a and b was 30m and the quota of a being lower than b.
